Study on Phase Formation Dynamics in Pseudo-Cell Space Measured by Time-resolved Microscope Spectroscopy

本课题的研究目的如下：1.建立胶束或聚合物微胶囊形成的拟细胞空间在显微镜下静置的方法。我们将建立将溶剂、液体晶体或聚合物混合物倒入由微操作器操作的伪细胞空间的技术。我们将建立可以通过显微镜图形、光谱和时间分辨衰减曲线来测量伪细胞空间中的相变现象的系统。我们将建立一种分析方法来讨论伪胞空间中的相变现象。基于准细胞空间中的反应场。1997年，我们研制了本研究项目的实验系统，如显微镜下的CCD摄像机图形控制我们原来的控制器、显微镜下的DSC数据、显微镜下的超快时间分辨光谱等。为此，我们在1998年建立了这一研究项目的分析系统，如显微镜下的CCD图形的计算机分析、显微镜下的时间分辨衰减曲线的计算机分析、显微镜下凝胶中小分子扩散系数的分析等。我们研究了PNIPA凝胶的体积相变过程和准晶胞空间中液体晶体的结构相变过程。在本研究中，我们发现了以下事实：1.在PNIPA凝胶的体积相变过程中，相分离过程是相互耦合的，我们发现可以用幂定律来分析这一现象。在PNIPA凝胶的体积相变过程中，存在两种类型的区域。SMAI分子的扩散系数值随PNIPA凝胶的收缩而减小。在本研究项目中，将有可能在赝胞空间中讨论其动力学机制。

The purpose of this research project was to perform these contents as follows ;1. We will establish the method which a pseudo-cell space made of micelle or polymer micro-capsule is sat up under microscope.2. We will establish the technique which solvent, liquid crtstal or polymer mixtures are poured into a pseudo-cell space operated by micromanipulator.3. We will establish the system which the phase transition phnomena in pseudo-cell space could be measured by microscope graphics, spectroscopy, and time-resolved decay curve.4. We will establish an analytical method in order to discuss the phase transition phenomena in pseudo-cell space. based on reaction field in pseudo-cell space.In 1997, we made the experimental system for this research project, for example, CCD camera graphics under microscope controlled our original theermo-controllor, DSC data under microscope, ultra-fast time-resolved spectrascopy under microscope, etc.. Hence in 1998, we made the analytical system for this research project, for example, computer analysis for CCD graphics under microscope, computer analysis for time-resolved decay curves under miceoscope, analysis of diffusion coefficient of small mollecules in gel under microscope, etc.. We studied to clarify the volume phase transition process of PNIPA gels and the structural phase transtion process of liquid crysstals in pseudo-cell space. At this research, we could find out the facts as follows ;1. In volume phase transition process of PNIPA gels, the phase separation process is coupling with one, We found out to be able to analyze this phenomenon using power law.2. In volume phase transition process of PNIPA gels, there are two type's domains.3. The values of diffusion coefficeint of a smaI molecule is decreasing with shrinking of PNIPA gels.In this research project, it will be possible to discuss the dynamical mechanism in pseudo-cell space.
